To a/ZZ whom t may concern,.-

Beit known that I, JOSEPH SILVERMAN, a

city and county of San Francisco and State of California, have invented new and vuseful Improvements in Telephone Attachments, of which the following is a specification.

-My invention relates toa telephone attachment, and especially to a device for hold` ing the receiver in suitable position relative `to the mouthpiece whereby both hands of` 'the operator may be left free. Its object is 'to provide a simple, practical, adjustable attachment for ordinaryhand and desk telephones which is adapted not only to hold the nect the telephone with the central'station. without the operator touchingthe hook, and which will allow the hook to remain up and 'leave the phone for an instant or call some one, but which attachment is so constructed that when one h-as ceased talking movin the head away allows the receiver to swing ack to center in front of the mouthpiece and the and break the circuit Y Y Y The main objection of the tele hone companies to the various receiv er-ho der attachments is .the liabilityl of leaving the. circuit 'ceiver' offfthe hookf.7 Y This difficulty lis obviated in my invention..Y l f The invention consists of the partsand the vconstruction and combination of parts, asl hereinafter more fully described 'and claimed, and having reference to the accompanyingl drawings, in which.-v Figure 1 is a side elevation of my device. Fig, 2l is a plan view of same. Y'

A represents va portablebase or stand pro'- vided with suitablemeans, as the vclam-pscrews 2, to receive and hold an ordinary hand-tele hone, asv 3. Extending -upward from this base is a post 41,l carryin the sliding bracket 5, in which the angu ar rocker member 6 is fulcrumed. This rocker member has a portion 6 to bear on the -ordinary telephone-hook 7, Which in telephones -unprovided with my attachment usually supports the receiver. A spring 8, connected to thebracket 5 andto the rock-arm or vderessor 6', tends to pull thearm and -hook gown, so as to close the circuit between the two electrodes 9 10 ,which are connected with Specication of Letters Patent.I

the apparatus. The pivot portion of the member 6 carries a projecting pin 11,' which normally engages in the crotch of a double orsymmetrically-forked cam member 12, which is carried by a sleeve 13, and which sleeve rests on the bracket 5 and is free to turn in .l

either direction on the post 1 1.

'Ihe bracket 5 is shown as bifurcated and the pin 11 as having a tubular portion or'collar 11a disposed between ,the forks of the bracket and embracing the corresponding 'part -of member 6. The collar and pin are lockedto member 6 by a set-screw 14. This construction enables the depressor V6 to be shiftedto vary the levera e on the telephonehook or to varythe oscilating movement of depressor.

The'sleev'e 13 carries an extendiblle lateral concentric with the pivot of block 17. A

spring 21, secured to block 17, bears on arm 18 and tendsl always to press the latter in against plate 16 and force the pin 19 into a hole! 20. The purpose of this perforated plate and hinged arm 18 is to adjust the receiver 22, which is carried by arm 18, to just the right elevation suited to the user of the telephone, while the extendible arm 15 allows the receiver to be moved out or in the'prop'er distancerelativelto the mouthpiece.

- The arm 18 carries a hinged louter end arranged to swing in a vertical plane; The outer end of this block is radially grooved, as shown at 24;, and a plate 25, having corresponding'projections 26 onits under side, is held a 'ainst the end of block 23 Vby the screw 27- an spring 28.' The tension of this spring-is such that the late 26 will always be pressedfhard against lock 23, and the engagement of the projection 26 with a groove 24 will keep the plate and the receiver 22 from turning when once adjusted to the right'inclination. f The receiver is held by suitable means, as the spring-clamping device 29, carried byplate 26.- Y l 4 5- Usuallytheparts are soarranged and adjusted thatv when the'telephone is not in use the arms l115 18 will-stand a .vertical plane abovethemouthpiece-30. i

lock 23 at its IOO IIO.

The cam member 12 is made forked in the manner shown, and each fork is so curved outward and oppositely that while the pin 11A forks of the cam to rock the pin l1 and al-4 low the hook to lift, thereby .connecting the telephone with central station, The cam branches are made suitably eccentric, so .that if the receiver-holding arm is swung far enough in either direction the pin will be ycarried onto a flatter portion, as 12a, of a cam to enable the operator to move away from the telephone or call some one without the hook being depressed and the connection broken, as would be the case if the receiver-arm swung back to center. With the pin l1,how.- ever, at any point intermediate the crotch of the cam and the .surfeoes .12e the spring 8 will operate through the depressor, pin l1, and the cam surfaces to bring the receiver arm to center and depress the hook. Another importent thiiigm this connection is that it takes such .e long movement, com .aretively, of the receiver to `olle side o the mouthpiece to .Gerry the pin onto e surfeee 12e, where the hook vis .allowed to .stay up Without pressure being maintained on the receiver, that one would never under ordi.- nary circumstances leave the .hook up after talking through the telephone, since it only takes a movement of the receiver of a couple of molles to one side or the other of the mouthpiece to lift the hook and to bring the lips opposite the mouthpiece with the receiver against the ear. The lifting of the hook and the connecting with central is sim- Ply delle by Pleomg .the eer .against the receiver and moving the head a little .to one side to bring the speakers lips opposite .the mouthpiece. through talking, moving the head away allows the receiver to swing back to center in front of the mouthpiece, and the hook is automatically depressed and the circuit broken. The reoeiverI needs never to be taken from its clamp 29- .No metter how forgetful or absentminded one may be. the moment the user leaves the phone, in case of course the receiverfarm is not deliberately swung away to one side to oeuse the pin to ride onto a part 12a, the orouit is broken. and there een be no suoli eomplamt as is the equivalent now of the receiver being off the hook.

The etteohment is applicable to any ordi.-.

nary hand-.telephone or wall-telephone hav,- in a hook to make and break the circuit.

t is. possible that various modifications in my invention may be mede Without departing from the principle thereof, and l .do not wish to be understood as limiting myself to the specific construction as herein shown and described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination with a telephone hook and mouthpiece, of a suitably-supported depressor for the hook, a receiver-holder having a movement laterally of the mouthpiece, and means including a member operated by the receiver-holder vand having a crotch with symmetrical `cam portions `at each side there- .of said depressor having a member normally engaging the crotch .of said member and actuated by the cam portions thereof Whichever way the receiverfholder is oscillated.

2. The combination with a hook and mouthpiece of a tele hone, of a suitably-suported receiver-holer having a movement yaterally of the mouthpiece, a hookdepressor and means actuated cordinatcly with the receiver-holder to operate the depressor said means including a member having `a crotch engaged by the hook-depressor and having, also, cam portions at each side of the crotch whereby the deprcssor is actuated whichever way the receiver-holder is os- Qilleted.

3. The combination with a telephone having a mouthpiece and a hook, of a hook-.depressor, an adjustable, extendiblc swinging receiver-holder, .and a'mcmbcr movable with the holder and having Ia central crotch in which the depressor normally engages, said member having cam portions at each side of the crotch whereby the depressor is actuated whichever way the receiver-holder is oscillated.

4. The combination with the hook and mouthpiece .of a telephone, of a hinged depressor, a hinged receiver-holder, a forked cam operated by the receiver-holder, and means carried by the depressor cngegcablc with said cam, whereby the depressor is actuated whichever way the receiver-holder is oscillated.

5. The combination with the hook and mouthpiece of a telephone, of an oscillating depressor for the hook, a receiver-holder mounted to swing from side to side of the mouthpiece, a forked com operable by the receiver-holder engaging a part on the depressor, and means for maintaining said part normally in the crotch of said cam.

6. The combination with the mouthpiece and hook of a telephone, of a receiver-holder having a movement laterally of the mouthpiece, means for actuating the hook and means includin a cam having a flattened seat for the hoo r-actuating means said cam tending to maintain the receiver-holder in a fixed normal position with the hook depressed.
